"I guess I happen to be attracted to high-frequency men," Perry jokes in Cosmopolitan's July issue.

What did the musician learn during her time as Mrs. Brand? "It feels like a hundred lifetimes ago, so it's like digging up an old grave. A lot of therapy has happened and a lot of understanding and growth," Perry reveals. "Sometimes you have to go through all this s--t to get your grips on life and figure out what the next boundaries in your love life are going to be. You have to go through the mud in order to find that peaceful place. In the long run, it was necessary for me to have more of a teammate."

Handler, who's written a book of essays about one-night-stands, then asks Perry the longest she's gone without sex. "Maybe six months or a year," the unattached singer replies. "I don't stay single for long."

Why is that? "I carry a lot of rose quartz, which attracts the male," she says. "Maybe I need to calm it down with the amethyst." Perry doesn't always make men wait to do the deed, either. "I'm not like Professor Higgins with my sex life," she says. "I'm not super strict. For ne, the most important thing about sex is connection." One-night-stands are no-go, however. "I've never been that way," she says.

That's when the light bulb turns on. "If I could bottle up oxytocin—that chemical that's released when you're having sex—and put it in a new perfume, I would do it for sure," says the "E.T." singer, who's already released two fragrances, Killer Queen and Purr. "I'm down for that chemical. It's important."
